Chandler Carruth 8470b5b812 [x86] Flip the sentinel values used in the target shuffle mask decoding ... to significantly more sane sentinels. Notably, everywhere else in the backend's representation of shuffles uses '-1' to represent undef. The target shuffle masks really shouldn't diverge from that, especially as in a few places they are manipulated by shared code. This causes us to lose some undef lanes in various test masks. I want to get these back, but technically it isn't invalid and there are a *lot* of bugs here so I want to try to establish a saner baseline for fixing some of the bugs by aligning the specific senitnel values used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218561 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-27 04:42:39 +00:00
